A catalyst surface may be exposed to strain due application of load or interfacing with a substrate large lattice mismatch. In order test the effect on catalytic efficiency, we use density functional theory + U (DFT U) model water oxidation expanded and contracted surfaces Ni1−xFexOOH alloy, one best known catalysts for splitting. We find that low amount iron content has similar as applying com...

Net water transport (NWT) in estuaries is important for, for example, salt intrusion and sediment dynamics. While NWT only determined by river runoff single channels, estuarine networks, it results from a complex interplay between tides residual flows. This study aims to disentangle the various contributions of these physical drivers networks investigate sensitivities variable forcing condition...

The O–O bond-formation mechanism in water oxidation is still ambiguous even now. In this issue of Chem, Wang and co-workers prove that on a Co-based electrocatalyst can switch from radical coupling pathway to nucleophilic attack when the applied potential lifted. oxygen evolution reaction (OER) paramount significance area solar energy conversion. It initial step photosynthesis produce dioxygen ...

Abstract In spite of recent moves to wean the world fossil fuels, coal remains main source power in many countries. Coal yards are prone spontaneous ignition, a problem faced every country that stores or transports coal. Depending on environment-temperature, ventilation, and rank coal-heating self-ignition can be longer shorter process, but possibility never entirely dismissed. A plethora studi...

We present the first results concerning synthesizer-driven high-harmonic generation that reach water-window region. This approach holds promise of offering greater spectral tunability in isolated attosecond pulses and at same time achieving higher photon-flux, required for attosecondresolved soft X-ray transient absorption experiments.

the relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. in this paper, the influence of different types of land use on surface water quality is investigated. rain events samples from different land use in the central plateau, iran, were analyzed for major ions. statistical analyses were employed to examine the statistical relati...
